Error Correction:
Earlier efforts to utilise this idea of refining character-sequence prediction can be found in automatic speech recognition (ASR) community. In works such as Rozovskaya [1]} and Hans [2]} preposition errors were detected using classifiers. Grammatical error correction was approached using statistical machine translation methods by Ng [3]}. Recently,the idea of using recurrent encoder-decoder architecture in conjunction with attention mechanism was presented by Xie [4]} to address complex orthographic errors. Later this idea was adopted by Guo [5]} for tasks related to ASR.
